I like the fact that no men has eyes. Means that these are only but depictions of men, purely for the fantasies that she has, also here men seem to be a bit simplistic... the girl characters are okay but it really lacks character in all of men here.
Just looked at the raws and at ch 124 there is a tiny fraction of Ai-chan x Onii-san interaction there for god knows how long of a completely absence of onii-san. So Ai-chan and Onii-san are still canon.
This thing goes nowhere. First 30 chapters are okay, after that all creative budget for story and character development apparently went into fanservice. Author probably felt the infinite money glitch, and went for the „eternal limbo” route lol
